The retention time of the material inside the vertical mill is less than one minute. • The blaine size adjustment of the finished product is very flexible, reliable and convenient. It can be achieved by adjusting the speed of the classifier. • Noise is quite lower in VRM when compared to a ball mill.

Fine particles have an extended retention time within the drying gases (up to the dust collector), which ensures a good drying performance. The drying rate, resp. drying need is directly reflected in the mill exhaust temperature. Water injection: At certain conditions, roller mills need water injection to stabilize the grinding bed.
